Preliminary study of light yield dependence on LAB liquid scintillator composition

Understand

Liquid scintillator (LS) will be adopted as the detector material in JUNO (Jiangmen Underground Neutrino Observatory).

• The energy resolution requirement of JUNO is 3%, which has never previously been reached.
• To achieve this energy resolution, the light yield of liquid scintillator is an important factor.
• PPO (the fluor) and bis-MSB (the wavelength shifter) are the two main materials dissolved in LAB.
